"[SOLVED] HELP : Eclipse shows errors before execution"

Hello,

I bought the White Paper "How to Extend RapidMiner 5.0" and I followed the steps shown in page 11 to create my own Extension. Unfortunately Eclipse shows errors before execution

: Project 'RapidMiner_Vega' is missing required source folder: 'src_test'

Help please.

Thank you.

Hi,

did you checkout the RapidMiner sourcecode here: https://rapidminer.svn.sourceforge.net/svnroot/rapidminer/Vega ?
It contains a src_test folder, so does your local version you checked out contain one as well? If not, please checkout the RM Vega project again.

Regards,
Marco

Thank you Marco Boeck.
Actually you're right!
Now eclipse shows another error :
The type DriverAdapter must implement the inherited abstract method Driver.getParentLogger() DriverAdapter.java /RapidMiner_Vega/src/com/rapidminer/tools/jdbc line 40
thank you for Help.

Hi,
the reason here is that you try to compile your Project with JDK 1.7. There has been a change in the interface "Driver" in this version and now it needs this new method.
The solution here is to compile RapidMiner with JDK 1.6 and everthing should work.

Hi,
Thank you Nils.
I compiled RapidMiner with JDK 1.6 and the error is gone.
Now I have some Warnings (100 of 191 items)... is this normal ? Can I continue my work ?
thank you for Help.

Hi,

indeed, Warnings are just warnings, so you can ignore them.
